Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina. It is one of the largest ...
Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur Argentinosaurus huinculensis, which is the largest dinosaur known from uncontroversial and relatively substantial evidence, estimated to have been 70–80 t (77–88 short tons) and 36 m (118 ft) long.

Yutyrannus was a large bipedal predator. The holotype and oldest-known specimen has an estimated length of 9 metres (29.5 ft) and an estimated weight of about 1,414 kilograms (3,117 lb). [ 1 ] In 2016, Gregory S. Paul gave lower estimations of 7.5 metres (24.6 ft) and 1.1 tonnes (1.2 short tons). [ 4 ]
The remains have been lost, but the sacrum drawing remains. It suggests a sacrum of almost 1.3 m (4.3 ft) long, [432] making it the largest dinosaur sacrum discovered so far, except those of Argentinosaurus and Apatosaurus. [433] In 2010, the femur of a large sauropod was discovered in France. The femur suggests an animal that grew to immense ...
Giraffatitan (name meaning "titanic giraffe") is a genus of sauropod dinosaur that lived during the late Jurassic Period (Kimmeridgian–Tithonian stages) in what is now Lindi Region, Tanzania. Only one species is known, G. brancai , named in honor of German paleontologist Wilhelm von Branca , who was a driving force behind the expedition that ...
It is among the longest dinosaurs ever discovered, with the three known specimens reaching 33–40 meters (108–131 ft) in length, with the largest individual possibly exceeding 40 meters (130 ft) in size. [4] [5] Mass estimates for the WDC and BYU specimens tend to be around 35–44 metric tons (39–49 short tons) in body mass. [5]
It is the largest-known member of the family Dromaeosauridae, measuring about 6–7 metres (20–23 ft) long and typically weighing up to 500 kilograms (1,100 lb). As a heavily built, ground-dwelling, bipedal carnivore , its large size and variety of unique features have earned it attention in both pop culture and the scientific community.
